================
Comment at: llvm/include/llvm/TargetParser/AArch64TargetParser.h:567-568

+// For given features returns a mask to check if CPU support them. The mask is
+// used in Function Multi Versioning resolver conditions code generation.
 uint64_t getCpuSupportsMask(ArrayRef<StringRef> FeatureStrs);
----------------
`CPUFeatures` has 60 entries, which means the return value here will overflow 
if we add a few more entries. We should probably have a `static_assert(FEAT_MAX 
<= 64)` in the implementation. Or should the `CPUFeatures` values actually be 
bitmasks, like ArchExtKind?
